Blue Screen stop error: 0X000000F4

I am using Windows Vista Pro on HP Pavilion a6167 desktop PC since past six months. It was working fine so far but don’t know what went wrong, since last week I have got BSOD thrice. I have no idea regarding this cause because I haven’t made any changes during this period.
